RELATED APPLICATIONS

This application claims the benefit of priority to U.S. Provisional Patent Application No. 62/222,667, filed Sep. 23, 2015, the disclosure of which is incorporated by reference herein in its entirety.

FIELD OF THE DISCLOSURE

This disclosure pertains to flavonoid compositions and methods of using such flavonoid compositions. More particularly, it pertains to flavonoid compositions that are formulated for use by human and/or animal subjects. The flavonoid compositions can include a flavonoid, for example, the flavonoid quercetin and/or derivatives of quercetin, in a form that can be easily administered to a human and/or animal subject. The flavonoid compositions can also be configured to increase the bioavailability, absorption, distribution, metabolism, and/or excretion of quercetin. The flavonoid compositions can also comprise other additives to increase the bioavailability, absorption, distribution, metabolism, and/or excretion of quercetin.

BACKGROUND

Phytochemicals are chemicals produced by plants, and include tannins, lignins, and flavonoids. The largest and best studied polyphenols are the flavonoids, with more than 8,000 identified and classified into at least six subgroups: flavonols, flavones, flavanones, flavanols (and their oligomers, proanthocyanidins), anthocyanidins, and isoflavonoids (Table 1) (USDA Nutrient Data Laboratory. USDA Database for the Flavonoid Content of Selected Foods. (2007) Beltsville, Md.: U.S. Dept. of Agriculture). Only about 100 polyphenols are in foods humans typically eat. Flavonoids are widely distributed in plants and function as plant pigments, signaling molecules, and defenders against infection and injury.

TABLE 1 Flavonoid Classification, Examples, and Sources Flavonoid Subgroup Specific Flavonoids Food Sources Flavonols Quercetin, kaempferol, onions, apples, leafy myricetin, isorhamnetin vegetables, berries Flavones Luteolin, apigenin parsley, hot peppers, celery, artichokes, spices Flavanones Hesperetin, naringenin, citrus fruits and citrus juices eriodictyol Flavan-3-ols Catechins, tea, chocolate, tree fruits, epigallocatechins, grape seed theaflavins Anthocyanidins Cyaniding, delphinidin, most berries, cowpeas malvidin, pelargonidin, peonidin, petunidin Isoflavones Daidzein, genistein, soybeans, soyfoods glycitein

Dietary intake of flavonoids ranges from 50 to 800 mg/day depending on the consumption of the food source containing various flavonoids. In the U.S., total flavonoid intake averages 251 mg/day (Chun O K, Floegel A, Chung S J, et al. Estimation of antioxidant intakes from diet and supplements in U.S. adults. J Nutr 2010; 140:317-24; the disclosure of which is incorporated by reference herein in its entirety), and in Spain 313 mg/day (Zamora-Ros R, Andres-Lacueva C, Lamuela-Raventós R M, et al. Estimation of dietary sources and flavonoid intake in a Spanish adult population (EPIC-Spain). J Am Diet Assoc 2010; 110:390-8; the disclosure of which is incorporated by reference herein in its entirety), with important sources including tea, citrus fruit and juice, beers and ales, wines, melon and berries, apples, onions, and bananas. Only about 29% of individuals consume tea on a given day, and without tea consumption, the flavonoid intake is closer to about 50 mg/day, reflecting the low intake of fruits and vegetables by U.S. adults. The typical American is a low consumer of fruit (0.53 cups/1000 calories) and vegetables (0.77 cups/1000 calories), well below the Healthy People 2020 goals of 0.90 cups/1000 calories for fruit and 1.14 cups/1000 calories for vegetables.

A high intake of fruits and vegetables has been linked in numerous studies to reduced risk of cardiovascular disease and various types of cancer. The disease-reducing influence of fruits and vegetables may be due in part to high levels of flavonoids (Hooper L, Kroon P A, Rimm E B, et al. Flavonoids, flavonoid-rich foods, and cardiovascular risk: a meta-analysis of randomized controlled trials. Am J Clin Nutr 2008; 88:38-50; Wang L, Lee I M, Zhang S M, et al. Dietary intake of selected flavonols, flavones, and flavonoid-rich foods and risk of cancer in middle-aged and older women. Am J Clin Nutr 2009; 89:905-12; Zamora-Ros R1, Rabassa M, Cherubini A, Urpí-Sardà M, Bandinelli S, Ferrucci L, Andres-Lacueva C. High concentrations of a urinary biomarker of polyphenol intake are associated with decreased mortality in older adults. J Nutr. 2013; 143:1445-50). A 12-year study of 807 elderly men and women in Italy showed that those in the upper tertile for total urinary polyphenol concentration (a proxy measure of fruit and vegetable intake) experienced a 30% reduction in all-cause mortality (Zamora-Ros R1, Rabassa M, Cherubini A, Urpí-Sardà M, Bandinelli S, Ferrucci L, Andres-Lacueva C. High concentrations of a urinary biomarker of polyphenol intake are associated with decreased mortality in older adults. J Nutr. 2013; 143:1445-50). These data strongly support that a high polyphenol intake is associated with extended longevity.

Many flavonoids possess strong anti-inflammatory, anti-viral, antioxidant, anti-obesity, and anti-carcinogenic properties when studied in vitro using large doses of the purified form. Inflammation and oxidative stress are key mechanisms in the pathogenesis of certain disease states, supporting the proposed strategy of increased flavonoid intake for prevention of cancer, diabetes mellitus, and cardiovascular disease. However, results from randomized, double-blinded studies in humans with large doses of purified flavonoids such as quercetin have been disappointing (Shanely R A, Knab A M, Nieman D C, et al. Quercetin supplementation does not alter antioxidant status in humans. Free Radic Res 2010; 44:224-31). Flavonoids vary widely in bioavailability, and most are poorly absorbed, undergo active efflux, and are extensively conjugated and metabolically transformed, all of which can affect their bioactive capacities (Zhang L, Zuo Z, Lin G. Intestinal and hepatic glucuronidation of flavonoids. Mol Pharm 2007; 4:833-45). Despite low bioavailability of the parent flavonoid, some of the in vivo metabolites may accumulate in tissues and produce bioactive influences, but conclusive human data are lacking. For example, animal data indicate that quercetin metabolites accumulate in the vascular tissue and there act as complementary antioxidants, with plasma albumin facilitating the translocation of quercetin metabolites to the vascular target (Terao J, Kawai Y, Murota K. Vegetable flavonoids and cardiovascular disease. Asia Pac J Clin Nutr 2008; 17(Suppl 1): 291-3).

There is a growing realization that bioactive influences of individual flavonoids are potentiated when mixed with other flavonoids (for example, the flavonol quercetin with the flavanol epigallocatechin 3-gallate (EGCG)) or included in a cocktail or extract of other polyphenols and nutrients (Lila M A. From beans to berries and beyond: teamwork between plant chemicals for protection of optimal human health. Ann N Y Acad Sci 2007; 1114:372-80). Two or more flavonoids ingested together may increase bioavailability and decrease elimination via competitive inhibition of glucuronide and sulfate conjugation in both the intestine and liver, and by inhibiting efflux transporters such as P-glycoprotein, breast cancer resistance protein (BCRP), and multidrug resistance protein 2 (MRP2) (Kale A, Gawande S, Kotwal S, et al. Studies on the effects of oral administration of nutrient mixture, quercetin and red onions on the bioavailability of epigallocatechin gallate from green tea extract. Phytother Res 2010; 24 (Suppl 1):S48-55).

The health-protective effects of plant foods are not produced by a single component but rather complex mixtures of interacting molecules (Lila M A. From beans to berries and beyond: teamwork between plant chemicals for protection of optimal human health. Ann N Y Acad Sci 2007; 1114:372-80). The polyphenols and natural components provide a multifaceted defensive strategy for both plants and humans. Thus the “pharma” approach of using large doses of a single bioactive molecule is seldom successful in the application of nutrition to human health and performance. Additionally, a metabolomics or nutrigenomics approach is needed to improve the capacity of investigators to capture the complex and subtle influences of flavonoid supplements or flavonoid-rich extracts, foods, and beverages on whole-body metabolism and physiology (Bakker G C, van Erk M J, Pellis L, et al. An antiinflammatory dietary mix modulates inflammation and oxidative and metabolic stress in overweight men: a nutrigenomics approach. Am J Clin Nutr 2010; 91:1044-59).

Quercetin is a flavonol compound that is found in many fruits and vegetables, such as red onions, capers, black plums, blueberries, and red applies. It has been reported to provide numerous health benefits to humans that ingest the compound. These reported health benefits include acting as a powerful antioxidant, improving athletic performance, improving cardiovascular health, and aiding in immune response. Some studies have found that quercetin can reduce blood pressure and LDL cholesterol. Other studies have found that quercetin can increase athletic performance.

Although quercetin can provide numerous benefits, many people may not be able to fully realize its benefits. For example, for many people there may not be a convenient source of quercetin available to them. In some cases, some people may not enjoy the taste and/or flavors of natural sources of quercetin. In other instances, some people may not be able to consume sufficient amounts of quercetin to receive a beneficial effect. In other cases, some people may not be able to consume quercetin in a manner that makes the quercetin bioavailable.

Therefore, challenges currently exist in realizing the benefits of quercetin. Accordingly, it would be an improvement in the art to provide compositions and methods to more fully realize the benefits of quercetin.

DETAILED DESCRIPTION

In some embodiments, the present application discloses flavonoid compositions and methods of using these flavonoid compositions. In other embodiments, the compositions and methods comprise compositions containing quercetin. In yet other embodiments, the methods comprise methods of preparing compositions containing quercetin. In some instances, the methods comprise methods of administering a composition of quercetin to a human and/or animal subject. The composition containing quercetin can comprise any effective amount of quercetin. The composition containing quercetin can also comprise one or more additive components configured to modulate the bioavailability, absorption, distribution, metabolism, and/or excretion of quercetin to increase a therapeutic effect of quercetin on the human and/or animal subject.

The term “subject” includes animals (for example, mammals, for example, cats, dogs, horses, pigs, cows, sheep, rodents, rabbits, squirrels, camels, bears, primates (for example, chimpanzees, gorillas, and humans)). It also includes transgenic animal models.

In some embodiments, polyphenols, flavonoids, flavonols, and quercetin are reported to provide health benefits. As described herein, polyphenols, flavonoids, flavonols, and quercetin are shown to prevent and/or treat heart disease, to help treat diabetes, to prevent and/or treat hypertension, to treat allergic reactions, to treat asthma, to treat arthritis, to prevent and/or treat cancer, to alleviate prostate problems, to improve athletic performance, to improve bone health, to strengthen immune response, to prevent fatigue, to reduce recovery time after exercise, to counter oxidative stress, and/or to boost energy.

In some embodiments, polyphenols, flavonoids, flavonols, and quercetin are administered to help athletes before, during, and/or after exercise. Polyphenols, flavonoids, flavonols, and quercetin can help athletes by increasing mitochondrial biogenesis, increasing endurance, and/or increasing performance.

As used herein, the term “polyphenols” refers to a compound containing more than one phenolic hydroxyl group. Polyphenols are a structural class of mainly natural, but also synthetic or semisynthetic organic chemicals characterized by the presence of large multiples of phenol structural units. Polyphenols are a classification of colorful phenolic organic compounds found in plants. As described herein, a high dietary intake of polyphenols reduce the risk for one or more of mortality, neurodegenerative diseases, weight gain, systemic inflammation and oxidative stress, diabetes, cardiovascular disease, hypertension, or acute respiratory illness.

As used herein, the term “flavonoids” refers to a group of plant metabolites that provide health benefits through cell signaling pathways and antioxidant effects. Flavonoids are polyphenolic molecules containing 15 carbon atoms and are soluble in water. Flavonoids are a subgroup within the polyphenols and function as natural antioxidants.

The flavonoid subgroup can be divided into six smaller groups including flavonols. As used herein, the term “flavonol” refers to phytochemical compounds found in high concentrations in a variety of plant-based foods and beverages. Based on their structure, they are classified as flavonoids and include the following compounds: quercetin, kaempferol, and myricetin.

As used herein, the term “quercetin” refers to a yellow crystalline pigment present in plants, and is used as a food supplement to reduce allergic responses or to boost immunity. Quercetin belongs to the flavonol group and can be found in a wide variety of fruits and vegetables. Quercetin can be found at least in the following fruits and vegetables: capers, lovage, dock like sorrel, radish leaves, carob fiber, dill, cilantro, Hungarian wax pepper, fennel leaves, red onion, radicchio, watercress, buckwheat, kale, chokeberry, cranberry, lingonberry, black plums, cow peas, sweet potato, blueberry, sea buckthorn berry, rowanberry, crowberry, prickly pear cactus fruits, red apples, broccoli, bilberry, tomatoes, black tea, and green tea. In some embodiments, pure quercetin may be extracted from the flowering genus of plants, Uncaria.

In some embodiments, quercetin can refer to aglycone quercetin (or quercetin aglycone). FIG. 1 illustrates embodiments of aglycone quercetin. Aglycone quercetin can refer to the quercetin backbone without any bound glucosyl or polysaccharide groups. Aglycone quercetin can also be referred to as 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-chromen-4-one. Aglycone quercetin can also be referred to as one or more of sophoretin, meletin, quercetine, xanthaurine, quercetol, quertine, and/or flavin meletin.

In some embodiments, quercetin refers to quercetin glucosides. Naturally occurring forms of quercetin can include quercetin glycosides. Quercetin glycosides can include rutin, (for example, rutoside, sophorin, and quercetin-3-O-rutinoside). Quercetin glycoside can also include quercitrin, which is a 3-O-a-L-rhamnoside. Quercetin glycoside can also include guaijaverin, which is a 3-O-arabinoside. Quercetin glycoside can also include hyperoside, which is a 3-O-galactoside. Quercetin glycoside can also include isoquercetin, which is a 3-O-glucoside. Quercetin glycoside can also include spiraeoside, which is a 4″-O-glucoside. Quercetin glycoside can also include miquelianin, which is a quercetin 3-O-B-d-glucuronopyranoside. FIG. 2 illustrates a quercetin glycoside, quercetin 4′-glucoside. FIG. 3 illustrates a quercetin glycoside, quercetin 3,4′-diglucoside.

In some embodiments, quercetin comprises any aglycone quercetin, any quercetin glycoside, and/or any quercetin derivative. Quercetin can be derived from any appropriate plant-based source. Quercetin can comprise any plant-based extract that is enriched in any aglycone quercetin, any quercetin glycoside, and/or any quercetin derivative. Quercetin can be extracted, isolated, and/or enriched by any appropriate methods as known in the art. Quercetin can comprise a mixture further comprising one or more of polyphenols, flavonoids, and/or flavonols.

In some embodiments, quercetin can have a generally low bioavailability upon ingestion. The generally low bioavailability can possibly be due to low absorption, rapid metabolism, and/or rapid elimination after ingestion. In other embodiments, absorption can be affected by differences in glycosylation, the makeup of the food matrix that contains the quercetin, and/or co-consumption of other food components such as fiber. In yet other embodiments, quercetin bioavailability increases with co-ingestion of other food components such as fats. In some cases, pure quercetin aglycone is absorbed differently than quercetin glycosides. In other cases, quercetin glycosides such as isoquercetin are more completely absorbed than quercetin aglycone. In some instances, simultaneous ingestion of quercetin with additives such as vitamin C, folate, and/or additional flavonoids improves the bioavailability of quercetin. Quercetin has a half-life of about 3.5-11 hours, and accumulates in the lungs, kidneys, heart, and liver.

The term “bioavailability” includes, generally, the degree to which a drug or other substance becomes available to a subject following ingestion, administration, or exposure. In one embodiment, for example, the bioavailability of the quercetin compounds may be the bioavailability to a particular target tissue. For example, in an embodiment, the particular target tissue may require traversal of the stomach or the small intestines, therefore the bioavailability data may be obtained from this particular target tissue.

The majority of dietary polyphenol intake reaches the colon. Polyphenols are subject to microbial degradation in the colon, converting polyphenols to simple phenols, and improving colon health and microbiome. Phenols can then be reabsorbed into the portal vein, which can be augmented with exercise, to the liver. In the liver, phenols undergo phase II biotransformation. The product is then released into circulation, where it exerts a beneficial bioactive effect before being excreted in the urine. As an example, the polyphenol, cyaniding, is converted to hydroxybenzoic acid by microbial degradation in the colon. Hydroxybenzoic acid is converted to hippuric acid through phase-2 conjugation. Hippuric acid is released into the bloodstream, and is eventually excreted in the urine. A high urine phenolic content reflects a high diet intake of polyphenols, and is linked to 30% lower mortality. Furthermore, a high diet consumption of flavonoids is associated with reduced risk of mortality in older women of about 60%.

In some embodiments, the flavonoid composition comprises one or more active ingredients, including: 100 mg quercetin, quercetin analogue and/or derivative, or preferably isoquercetin, or combinations thereof (for example, at least about 50% each of quercetin and isoquercetin), 90-180 mg epigallocatechin 3-gallate (EGCG) with green tea extract, 120-240 mg blueberry anthocyanidins from extract, 100 mg caffeine, 100 mg N3-PUFA (60 mg DHA, 40 mg EPA), and 100 mg vitamin C. In other embodiments, the flavonoid composition comprises any other additive that is effective for increasing the bioavailability of the quercetin.

In some embodiments, the flavonoid composition includes a flavonoid other than or in addition to quercetin, for example, one or more flavonoid as described in Table 1 or other flavonoid.

In some embodiments, the flavonoid is present in an amount of about 52 mg.

In some embodiments, the flavonoid composition further comprises an antioxidant. As used herein, the term “antioxidant” refers broadly to a molecule that inhibits the oxidation of other molecules. In some embodiments, an antioxidant, as used herein, refers to green tea extract and its molecular components, which can include, for example, epigallocatechin (EGC), epicatechin gallate (ECG), epigallocatechin gallate (EGCG), epicatechin (EC), and flavonoids, such as kaempferol, quercetin, and myricetin. In some embodiments, the antioxidant is present in an amount of 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, 300, 310, 320, 330, 340, 350, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, or 500 mg or greater, or a value within a range defined by any two of the aforementioned values.

As further examples of such modes of administration and as further disclosure of modes of administration, disclosed herein are various methods for administration of the disclosed compositions including modes of administration through intraocular, intranasal, and intraauricular pathways.

The therapeutically effective amount of the ingredients disclosed herein required as a dose will depend on the route of administration and the physical characteristics of the specific human under consideration. The dose can be tailored to achieve a desired effect, but will depend on such factors as weight, diet, concurrent medication and other factors, which those skilled in the medical arts will recognize.

In practicing the methods of the disclosure, the products or compositions can be used alone or in combination with one another or in combination with other therapeutic or diagnostic agents. These products can be utilized in vivo, ordinarily in a mammal, preferably in a human, or in vitro. In employing them in vivo, the products or compositions can be administered to the mammal in a variety of ways, including parenterally, intravenously, subcutaneously, intramuscularly, colonically, rectally, vaginally, nasally or intraperitoneally, employing a variety of dosage forms. Such methods may also be applied to testing chemical activity in vivo.

As will be readily apparent to one skilled in the art, the useful in vivo dosage to be administered and the particular mode of administration will vary depending upon the age, weight and mammalian species treated, the particular ingredients employed, and the specific use for which these ingredients are employed. The determination of effective dosage levels, that is the dosage levels necessary to achieve the desired result, can be accomplished by one skilled in the art using routine therapeutic methods. Typically, human clinical applications of products are commenced at lower dosage levels, with dosage level being increased until the desired effect is achieved. Alternatively, acceptable in vitro studies can be used to establish useful doses and routes of administration of the compositions identified by the present methods using established therapeutic methods. In non-human animal studies, applications of potential products are commenced at higher dosage levels, with dosage being decreased until the desired effect is no longer achieved or adverse side effects disappear.

The dosage of active ingredient(s) may range broadly, depending upon the desired affects and the therapeutic indication. Typically, dosages of active ingredient(s) may be between about 10 microgram/kg and 100 mg/kg body weight, preferably between about 100 microgram/kg and 10 mg/kg body weight. Alternatively dosages may be based and calculated upon the surface area of the patient, as understood by those of skill in the art. Administration is preferably oral on a daily or twice daily basis. Administration may include four tablets taken by mouth daily. In some embodiments, tablets may be administered during a meal time. In some embodiments, two tablets may be administered during a meal. In some embodiments, two tablets may be administered at breakfast and two at lunch.

The exact formulation, route of administration and dosage can be chosen in view of the consumer's condition. See for example, Fingl et al., in The Pharmacological Basis of Therapeutics, 1975, which is incorporated herein by reference in its entirety. The magnitude of an administrated dose may vary with the severity of a particular medical or physical condition and the route of administration. The severity of a condition may, for example, be evaluated, in part, by standard prognostic evaluation methods. Further, the dose and perhaps dose frequency may also vary according to the age, body weight, and response of the individual. A program comparable to that discussed above may be used in veterinary medicine.

The combined active ingredients in the compositions disclosed herein may be orally or non-orally administered to a human patient in the amount of about 10 mg/day to about 1,000 mg/day of the total active ingredients, and more preferably about 50 mg/day to about 400 mg/day of the total active ingredients at, one time per day or in other embodiments, over two to about ten times per day. Nonetheless, as will be understood by those of skill in the art, in certain situations it may be necessary to administer the active ingredients disclosed herein in amounts that excess, or even far exceed, the above-stated, preferred dosage range to treat effectively and aggressively a desired condition or characteristic.

Ingredients disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular compound or ingredient, or of a subset of the compounds, sharing certain chemical moieties, may be established by determining in vitro toxicity towards a cell line, such as a mammalian, and preferably a human, cell line. The results of such studies are often predictive of toxicity in animals, such as mammals, or more specifically, humans. Alternatively, the toxicity of particular compounds or ingredients in an animal model, such as mice, rats, rabbits, or monkeys, may be determined using known methods. The efficacy of a particular compound may be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. Recognized in vitro models exist for nearly every class of condition, including the conditions abated by the compounds or ingredients disclosed herein, including obesity. Similarly, acceptable animal models may be used to establish efficacy of chemicals to treat such conditions. When selecting a model to determine efficacy, the skilled artisan can be guided by the state of the art to choose an appropriate model, dose, and route of administration, and regime. Of course, human clinical trials can also be used to determine the efficacy of a compound or ingredient in humans.

The active ingredients described above may be used alone or in combination with one another, or in combination with other therapeutic or diagnostic agents. These products can be utilized in vivo or in vitro. The useful dosages and the most useful modes of administration will vary depending upon the age and weight of the consumer, the particular ingredients employed, and the specific use for which these ingredients are employed.

A flavonoid composition was prepared by combining the following active ingredients, in the listed amounts in Table 3. The quantity of each ingredient was confirmed at four weeks and at twelve weeks.

TABLE 3 Flavonoid Tablet Composition Assay Method mg/one tablet mg/four tablets Total Phenolics Folin Ciocaltue 104.25 ± 1.4 417.0 ± 5.7 (gallic acid equivalent) assay Total DMAC assay  15.1 ± 0.8  60.3 ± 3.1 Proanthocyanidin (procyanidin B2 equivalent) Total Anthocyanins HPLC_(520 nm)  16.3 ± 1.0  65.2 ± 4.0 (cyaniding-3-glucoside (38.6 aglycone) equivalent) Epigallocatechin HPLC_(280 nm)  21.4 ± 1.3  85.6 ± 5.2 Gallate (EGCG) Quercetin HPLC_(360 nm)  23.9 ± 2.1  95.6 ± 8.4 Caffeine HPLC_(280 nm)  24.8 ± 1.1  99.1 ± 4.4

The ingredients were combined to prepare a tablet. The tablet has a serving size of 4, with the following per serving: 50 calories, 12 grams of carbohydrate (4% of daily value), 10 grams of sugars, 100 mg of vitamin C (as ascorbyl palmitate; 167% of daily value), 156 mg of wild bilberry fruit extract (std. min. 25% total anthocyanins), 180 mg green tea leaf extract, 100 mg of quercetin, 100 mg natural caffeine (from Coffea Arabica bean), and 200 mg NovoOmega® Omega-3 F30 powder (std. 30% omega-3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid)). Additional ingredients may include sugar, natural and artificial flavors, dextrose, cellulose gum, sucralose, bamboo whole plant extract, guar gum, xanthan gum, citric acid, malic acid, and L-tartaric acid. The tablet more than doubles the normal flavonoid intake and provides a more diverse array of flavonoids than typical.

Example 3 Influence of Ingesting a Flavonoid-Rich Supplement on the Human Metabolome and Concentration of Urine Phenolics

The following example demonstrates the effects of ingesting a flavonoid-rich composition in overweight or obese subjects.

This study measures the effect of ingesting a flavonoid-rich supplement on various biomarkers in overweight/obese women during a 12-week period. The flavonoid-rich supplement contains a mixture of flavonoids including quercetin, catechins from green tea extract, and anthocyanins from blueberry extract, and other food components that facilitate flavonoid bioactivity including fish oil, caffeine, and vitamin C.

The primary objective of this study is to evaluate the effect of ingesting a flavonoid-rich supplement on total urine polyphenol concentration and shifts in blood metabolites related to flavonoid intake in healthy but overweight/obese community-dwelling adults. Subjects in the flavonoid supplement group achieve high urine polyphenol concentrations.

Secondary objectives are to determine related effects on measures of inflammation and oxidative stress. Chemistry profiles and symptom logs are compared pre- and post-study between groups to confirm prior safety data collected on human participants.

Subjects randomized to ingestion of the flavonoid-rich supplement compared to placebo will experience an increase in total urine polyphenols concentrations and shifts in blood metabolites related to increased flavonoid metabolism. Secondarily, subjects ingesting the flavonoid-rich supplement will experience a decrease in systemic inflammation and oxidative stress.

The following details demonstrate the effect of ingesting a flavonoid-rich supplement on blood metabolite shifts and urine phenolics during a 12-week period in overweight and/or obese women.

The characteristics for the control (placebo) group and test group (flavonoid composition) are provided in Table 4.

TABLE 4 Subject Characteristics Flavonoid (N = 51) Placebo (N = 52) Mean SD Mean SD P-Value Age (yr) 50.3 11.2 50.3 14.0 0.986 Height (in) 63.9 2.0 64.5 2.5 0.199 Weight (lbs) 186 39.0 191 40.8 0.516 Body Mass Index 32.1 6.6 32.5 7.1 0.759 Body Fat (%) 42.0 7.3 41.9 7.4 0.972 C-reactive protein 4.66 4.8 4.89 5.5 0.823 (mg/L) Glucose (mg/dL) 95.7 15.9 96.4 17.5 0.855

Subjects were administered a flavonoid composition as described in Example 2 (flavonoid tablet) or a placebo, with 4 tablets each day for a 12-week period. Two tablets were administered at breakfast and two tablets were administered at lunch.

Prior to the study, subjects were asked to respond to a survey to determine their symptoms or feelings during the previous 4-week period. At the end of the study, the subjects were asked to complete the same survey. As shown in Table 5, subject responses were generally identical prior to and following the survey, indicating that the composition did not result in side effects.

As depicted in FIGS. 5A-5D, subjects that were administered the flavonoid composition had elevated diet flavonoid intake, elevated diet EGCG, elevated diet anthocyanins, and elevated diet quercetin (flavonoid subjects depicted on the left, and control subjects on the right). Furthermore, as shown in FIG. 6, total urinary phenolics increased with subjects that were administered the flavonoid composition as compared to the control (flavonoid subjects depicted on the left, and control subjects on the right).

The flavonoid tablets were analyzed for phenolic content at weeks 4 and 12 of the study, and all ingredients were stable at pre-study values. The supplement increased total diet flavonoid intake by 181%, and provided a more diverse cocktail of flavonoids (anthocyanins, EGCG, quercetin) than typically ingested. This increase in dietary flavonoid intake translates to a significant decrease in mortality over time. Urine phenolic measurements showed a significant 23% increase in the flavonoid compared to placebo group during the 12-week study (interaction effect, P=0.041). This increase translates to a significant decrease in mortality over time. Flavonoid and placebo groups did not differ after the 12-week study in symptoms (except for small heartburn effect), or serum diagnostic chemistries, indicating that ingestion of the flavonoid composition vs. placebo is not related to adverse side-effects.
